555a5ea9dd basetsmux: use private copy of g_ptr_array_copy 
This function is only present since glib 2.62

c2eeb639b0 basetsmux: fix SCTE pts_adjustment with offsets 
When there are elements between the demuxer and the muxer that
introduce an offset to the running time, or when offsets are
set on pads by the application, this shift must be taken into
account when calculating the final pts_adjustement.

c3a161f287 basetsmux: rework SCTE section handling to handle passthrough 
mpegtsmux can receive SCTE sections from two origins: events
created by the application, and events forwarded downstream by
mpegtsdemux, containing sections that may not have been fully
parsed, and additional data to help tsmux translate times to
the correct domain, both for requesting keyframes and calculating
an accurate pts_adjustment.

The complete approach is documented further in a comment above
the relevant function.

e4f40ba526 mpegtspacketizer: handle "packetizing" already packetized data 
.. when the section didn't have a packetizer. This can happen
as a result of building a new section from a copy of the original
data of another section.

4af003bc02 tsdemux: switch SCTE 35 sections handling to a passthrough model 
Instead of modifying the splice times in the incoming sections
to running time and expecting eg mpegtsmux to convert those back
to its local PES time domain, which might be impossible when
those splice times are encrypted or the specification is extended,
transmit the needed information to the muxer as separate fields in
the event:

* A pts offset field can be used by the muxer in order to calculate
  a final pts_adjustment

* A rtime_map can be used by the muxer to determine the correct
  running times at which it should request keyframes

d17c7f25e6 scte35-section: semantic API break 
Document that the constructors for the splice events expect
a running time, as users of the API can not be expected to

be4d0fff23 basetsmux: extend SCTE 35 support 
Makes it possible to support passing SCTE 35 cue points from
demuxer to muxer, while preserving correct timing.

This will also improve ex nihilo cue points injection, as splice
times and durations are now interpreted as running time values,
and may trigger key unit requests.

a03c395582 mpegtssection: expose event constructor 
This allows the demuxer to forward sections of interest downstream,
for example SCTE 35 splice information. These can then be reinjected
appropriately by a muxer for example.

This renable at meson setup time the installation of the gst-indent
commit hook. The hooks were kept from gst-devtools as this set supports
both C checks and Python checks.

091946a478 ci: Port CI to the new monorepo 
Main differences with previous setup are:
- No manifest creation
- gst-indent is executed only when the bot is assigned (instead of the manifest task)
- Cerbero jobs are triggered in the cerbero repo
- Remove cerbero and android related files as they now are in cerbero
  itself.
- Update `container.ps1` to the new file layout
